[0042] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0043] As shown in the drawings, the continuous press-in equipment in the embodiment includes a rotating nut press-in device 100, a C-shaped ring press-in device 200, a conveying line 300, and a robot 400. Figure 1

[0044] The downstream end of the conveying line 300 extends to the rotating nut press-in device 100 to provide an intermediate product in the rotor assembly process, hereinafter referred to as a rotor intermediate product, to the rotating nut press-in device 100. The rotor intermediate product refers to the intermediate form of the rotor in the assembly process, and the rotor intermediate product has already assembled a rotating variable device, which needs to be fixed on the axis by a nut and a C-shaped ring. In an embodiment, the conveying line 300 can be a chain and sprocket type conveying line 300, that is, a motor drives the rotation of a sprocket, and the sprocket further drives the circular motion of a chain, so that the rotor intermediate product in the clamp on the chain is transported with the chain.

[0045] The rotating nut press-in device 100 is used for continuous feeding and press-fitting of a rotating nut, so as to assemble the rotating nut on the assembly end of the rotor intermediate product. The C-shaped ring press-in device 200 is arranged side by side downstream of the rotating nut press-in device 100, and is used for continuous feeding and press-fitting of a C-shaped ring, so as to continue to press-fit the C-shaped ring on the rotor intermediate product assembled with the rotating nut, and further realize axial locking of the rotating variable device in the rotor intermediate product.

[0046] The robot 400 is used for transferring the rotor intermediate product press-fitted with the rotating nut from the rotating nut press-in device 100 to the C-shaped ring press-in device 200. The robot 400 is located on one side of the rotating nut press-in device 100 and the C-shaped ring press-in device 200, and the movement stroke of the robot 400 covers the rotating nut press-in device 100 and the C-shaped ring press-in device 200.

[0047] As shown in the drawings, the continuous press-in equipment in the embodiment includes a rotating nut press-in device 100, a C-shaped ring press-in device 200, a conveying line 300, and a robot 400. Figure 2 ​As shown, the rotating nut pressing device 100 comprises a first conveying mechanism 10, a first pressing mechanism 20 and a first feeding mechanism 30. The first pressing mechanism 20 is located between the first conveying mechanism 10 and the first feeding mechanism 30. The first conveying mechanism 10 is used to realize the feeding of the intermediate product in the rotor assembly process; the first feeding mechanism 30 is used to realize the feeding of the rotating nut; and the first pressing mechanism 20 is used to receive the rotating nut and the rotor intermediate product and press the rotating nut on the rotor intermediate product.

[0048] The first conveying mechanism 10 comprises a first fixed jig 11 and a first power unit 12. The first power unit 12 can drive the first fixed jig 11 to reciprocate along the X-axis direction between the first feeding station and the first pressing station where the first pressing mechanism 20 is located. In this way, the rotor intermediate product at the first feeding station can be conveyed to the first pressing station for pressing.

[0049] As shown in Figure 3 , the first fixed jig 11 is used to fix the rotor intermediate product that needs to be fed, and correspondingly, the first fixed jig 11 is provided with a fixed groove suitable for placing the rotor intermediate product. The first power unit 12 comprises an X-axis linear motor 121 and an X-axis guide rail 122. The X-axis linear motor 121 is located on one side of the first fixed jig 11, the slider of the X-axis linear motor 121 is in transmission connection with the first fixed jig 11, and the first fixed jig 11 is driven to reciprocate along the X-axis guide rail 122.

[0050] As shown in Figure 4 , 5 , the first feeding mechanism 30 comprises a feeding conveying line 31 and a turnover unit 32. The feeding conveying line 31 is located on one side of the first pressing mechanism 20, and the turnover unit 32 is located between the feeding conveying line 31 and the first pressing mechanism 20. The rotating nuts provided by the feeding conveying line 31 can be conveyed to the first pressing station by the turnover unit 32.

[0051] The feeding conveying line 31 comprises a feeding jig 311, a Y-axis linear motor 312 and a Y-axis guide rail 313.

[0052] The feeding jig 311 comprises a plurality of columns 314 for stacking the rotating nuts. The plurality of columns 314 are arranged side by side on a base plate along the Y-axis direction. The slider of the Y-axis linear motor 312 is in transmission connection with the base plate, and the base plate is driven to reciprocate along the Y-axis guide rail 313. In this way, the Y-axis linear motor 312 can drive the columns 314 stacked with rotating nuts to move to the turnover unit 32 in sequence, so that the turnover unit 32 can realize the continuous feeding of a plurality of groups of stacked rotating nuts.

[0053] In order to enable the rotation nut stacked on the column 314 to be sequentially lifted to a height suitable for the turnover unit 32 to grab, the upper feeding jig 311 further comprises a pushing ring 315, a Z-axis sliding rail 316 and a rotation motor 317.

[0054] The Z-axis sliding rail 316 is vertically arranged on one side of the column 314, and the lower end of the column 314 is drivingly connected with the rotation motor 317. The surface of any column 314 is axially uniformly provided with threads, and the pushing ring 315 is sleeved on the column 314 and matched with the threads. The pushing ring 315 extends into the sliding groove of the Z-axis sliding rail 316 and moves up and down along the sliding groove with the pivoting of the column 314. In this way, when the rotation motor 317 works, it can drive the column 314 drivingly connected therewith to pivot synchronously. At the same time, the pushing ring 315 can move upward along the threads on the column 314, thereby gradually pushing the rotation nut stacked on the column 314 upward, so that there is always a rotation nut at the material taking position, thus facilitating the turnover unit 32 to continuously grab the rotation nut at the material taking position.

[0055] The turnover unit 32 comprises a material suction manipulator 321, a turnover manipulator 322, a translation cylinder 323, a lifting cylinder and a turnover table 325. The turnover table 325 is located between the upper feeding conveying line 31 and the first press-in station, and is used for temporarily storing the rotation nut that needs to be turned over. Correspondingly, the surface of the turnover table 325 is provided with a boss suitable for sleeving the rotation nut. The material suction manipulator 321 and the turnover manipulator 322 are spaced apart along the X-axis direction and arranged on a base plate above the turnover table 325.

[0056] The material suction manipulator 321 has a suction nozzle for sucking the rotation nut. The material suction manipulator 321 is connected with the base plate through a connecting arm, and a buffer spring 3211 is further arranged between the material suction manipulator 321 and the connecting arm. The turnover manipulator 322 comprises a suction nozzle 326, a rotating arm 327 and a turnover motor 328. The turnover motor 328 is connected with the suction nozzle 326 through the rotating arm 327 and drives the suction nozzle 326 to pivot within an angle range of 0 to 180°. In this way, after the suction nozzle 326 takes the material, the turnover motor 328 can drive the rotating arm 327 and the suction nozzle 326 thereon to turn over 180°, so that the sucked rotation nut is arranged upward, thereby facilitating the rotation nut to be sent to the first press-in station for press fitting.

[0057] The translation cylinder 323 is drivingly connected with the base plate, so that the translation cylinder 323 can drive the material suction manipulator 321 to reciprocate between the upper feeding conveying line 31 and the turnover table 325, thereby enabling the material suction manipulator 321 to grab the rotation nut from the upper feeding conveying line 31 and continuously place the rotation nut on the turnover table 325.

[0058] Meanwhile, the translation cylinder 323 can also drive the flipping robot 322 to reciprocate between the turnover table 325 and the first pressing station, thereby enabling the flipping robot 322 to grab the rotary nut on the turnover table 325 and rotate it to the first pressing station for continuous pressing.

[0059] The lifting cylinder is connected to the suction robot 321, the flipping robot 322, and the translation cylinder 323 to form an integrated transmission system, which drives the entire system to move up and down. This facilitates the suction robot 321 and the flipping robot 322 to descend to the corresponding material picking position to pick up the material, and after picking up the material, they rise to separate from the turnover table 325 to facilitate the feeding of the rotary nuts.

[0060] The first pressing mechanism 20 is located at the first pressing station and includes a first pressing head 21 and a first Z-axis cylinder 22. The first pressing head 21 is tractively connected to the first Z-axis cylinder 22, which drives the first pressing head 21 to move up and down above the first pressing station. Thus, the first Z-axis cylinder 22 can drive the first pressing head 21 to continuously press the resolver nut onto the assembly end of the rotor intermediate. Correspondingly, the end face of the first pressing head 21 is contoured to the assembly end to facilitate pressing the resolver nut onto the assembly end.

[0061] To facilitate the fixing of the first Z-axis cylinder 22 and improve the stability of its movement, the first pressing mechanism 20 further includes a fixed base 23, a lifting base 24, and guide columns 25. The fixed base 23 is supported by the guide columns 25. The first Z-axis cylinder 22 is mounted on the fixed base 23. The lifting base 24 is slidably fitted onto the guide columns 25 and connected to the output end of the first Z-axis cylinder 22. The first pressing head 21 is connected to the bottom surface of the lifting base 24. The lifting base 24 is fitted onto the four guide columns 25 via bushings. Therefore, when the first Z-axis cylinder 22 is working, it can move up and down along the four guide columns 25 via the lifting base 24, thereby ensuring that the rotary nut can be pressed vertically.

[0062] like Figure 6 As shown, the C-ring pressing device 200 includes a second conveying mechanism 40, a second pressing mechanism 50, and a second feeding mechanism 60. The second pressing mechanism 50 is located between the second conveying mechanism 40 and the second feeding mechanism 60. The second conveying mechanism 40 is used to feed intermediate products during rotor assembly; the second feeding mechanism 60 is used to feed C-rings; and the second pressing mechanism 50 is used to receive C-rings and rotor intermediate products and press the C-rings onto the rotor intermediate products.

[0063] The second conveying mechanism 40 comprises a second fixed jig 41 and a second power unit 42. The second power unit 42 is capable of driving the second fixed jig 41 to reciprocate along the X-axis direction between the second feeding station and the second press-in station where the second press-in mechanism 50 is located. In this way, the rotor intermediate product at the second feeding station can be conveyed to the second press-in station for press fitting.

[0064] As shown in Figure 7 , the second fixed jig 41 is used to fix the rotor intermediate product that needs to be fed, and correspondingly, the second fixed jig 41 is provided with a fixed groove suitable for placing the rotor intermediate product. The second power unit 42 comprises an X-axis linear motor 421 and an X-axis guide rail 422. The X-axis linear motor 421 is located on one side of the second fixed jig 41, and the slider thereof is in transmission connection with the second fixed jig 41 and drives the second fixed jig 41 to reciprocate along the X-axis guide rail 422.

[0065] As shown in Figure 8 , 9 , the second feeding mechanism 60 comprises a feeding unit 61 and a pushing unit 62.

[0066] The feeding unit 61 is used to provide the C-shaped ring to be press fitted in a feeding manner, and comprises a receiving table 611 and a feeding column 612. The feeding column 612 is located on the receiving table 611, and a plurality of C-shaped rings to be press fitted are stacked on the feeding column 612. The feeding column 612 is located on the receiving table 611 and can be driven by the pushing unit 62 to reciprocate along the Y-axis direction between an initial position and a feeding position. In this way, when the feeding column 612 moves from the initial position to the feeding position, the C-shaped rings stacked thereon can fall onto the receiving table 611 in sequence, thereby realizing continuous feeding of the C-shaped rings.

[0067] In order to facilitate the C-shaped rings stacked on the feeding column 612 to fall in sequence, in an embodiment, two feeding columns 612 are provided, and the two feeding columns 612 are arranged side by side on a gantry 613 along the Y-axis direction, so that two groups of C-shaped rings can be fed in sequence. At this time, the upper end of any one of the feeding columns 612 is fixedly connected to the upper cross beam of the gantry 613 where it is located, and the lower end of any one of the feeding columns 612 extends into the feeding port of the lower cross beam of the gantry 613 where it is located. In this way, the C-shaped rings stacked on the feeding column 612 can fall in sequence through the feeding port.

[0068] The receiving table 611 is used to receive the C-shaped rings from the feeding column 612 and circulate the C-shaped rings to the press fitting position.

[0069] Specifically, the material receiving platform 611 is slidingly arranged on the lower surface of a base plate 614, and the height of the base plate 614 corresponds to the pressing height of the second pressing mechanism. The material receiving platform 611 is driven by the material pushing unit 62 to reciprocate along the X-axis direction between the initial position and the second pressing position.

[0070] The material receiving platform 611 is provided with a feeding groove 615 passing through the upper and lower surfaces thereof towards the edge of the second pressing mechanism. In this way, when the material receiving platform 611 moves to the second pressing position, the C-shaped ring in the feeding groove 615 can be clamped on the assembly end of the rotor intermediate product in the assembly direction. Since the material receiving platform 611 is arranged on the lower surface of the base plate 614, in order to enable the C-shaped ring to fall into the feeding groove 615, the base plate 614 is provided with a hollow area exposing the feeding groove 615. Thus, when the material falling column 612 moves above the hollow area, the lowermost C-shaped ring is separated from the base plate 614 and falls into the lower feeding groove 615 through the hollow area.

[0071] In order to enable the C-shaped ring to be smoothly clamped on the assembly end of the rotor intermediate product, in an embodiment, the caliber of the feeding groove 615 is slightly larger than the diameter of the C-shaped ring, and the height of the feeding groove 615 is equal to the thickness of a C-shaped ring. In this way, it is ensured that only one C-shaped ring can be accommodated in the feeding groove 615, and thus the material receiving platform 611 can clamp only one C-shaped ring on the assembly end of the rotor intermediate product at a time.

[0072] Meanwhile, in order to enable the C-shaped ring to be stably accommodated in the feeding groove 615 before clamping, the bottom surface of the feeding groove 615 is further provided with a step for supporting the C-shaped ring. In this way, when the C-shaped ring is located in the feeding groove 615, the step in the feeding groove 615 can support the C-shaped ring in the vertical direction.

[0073] The material pushing unit 62 is used to drive the material falling unit 61 to feed, and includes an X-axis cylinder 621 and a Y-axis cylinder 622. The Y-axis cylinder 622 is fixed to the upper surface of the base plate 614 and drives the material falling column 612 to reciprocate along the Y-axis direction between the initial position and the feeding groove 615. The X-axis cylinder 621 is fixed to the lower surface of the base plate 614 and drives the material receiving platform 611 to reciprocate along the X-axis direction between the initial position and the second pressing position. In order to facilitate the movement of the material falling column 612 and the material receiving platform 611, the lower surface of the base plate 614 is further provided with an X-axis sliding rail 623 suitable for the reciprocating sliding of the material receiving platform 611, and the upper surface of the base plate 614 is further provided with a Y-axis sliding rail 624 suitable for the reciprocating sliding of the material falling column 612.

[0074] As shown in FIG. 6, the material falling column 612 is provided with a plurality of C-shaped rings 613 arranged in the assembly direction. The C-shaped rings 613 are arranged in the assembly direction on the material falling column 612, and the assembly direction is perpendicular to the direction in which the material falling column 612 moves. Figure 6 , 7As shown, the second pressing mechanism 50 is located at the second pressing station, which comprises a second pressing head 51 and a second Z-axis cylinder 52. The second pressing head 51 is in transmission connection with the second Z-axis cylinder 52, and the second Z-axis cylinder 52 drives the second pressing head 51 to perform lifting movement above the second pressing station. Thus, the second Z-axis cylinder 52 can drive the second pressing head 51 to continuously press the C-shaped ring on the assembly end of the rotor intermediate product. Correspondingly, the end face of the second pressing head 51 is shaped with the assembly end, so as to press the C-shaped ring on the assembly end.

[0075] In order to facilitate the fixation of the second Z-axis cylinder 52 and improve the stability of movement, the second pressing mechanism 50 further comprises a fixing seat 53, a lifting seat 54 and guide columns 55. At this time, the fixing seat 53 is supported by the guide columns 55, the second Z-axis cylinder 52 is arranged on the fixing seat 53, the lifting seat 54 is slidingly sleeved on the guide columns 55 and connected with the output end of the second Z-axis cylinder 52, and the second pressing head 51 is connected to the bottom surface of the lifting seat 54. At this time, the lifting seat 54 is sleeved on the four guide columns 55 through a shaft sleeve. Thus, when the second Z-axis cylinder 52 works, the lifting seat 54 can be lifted along the four guide columns 55, so as to ensure that the C-shaped ring can be vertically pressed.

[0076] In summary, in the continuous pressing equipment, the first conveying mechanism is arranged to realize the feeding of the rotor intermediate product, the first feeding mechanism is arranged to realize the translation and overturning feeding of the rotating variable nut, and the first pressing mechanism is arranged to realize the continuous assembly of the rotating variable nut. Further, the second conveying mechanism is arranged to realize the feeding of the rotor intermediate product assembled with the rotating variable nut, the second feeding mechanism is arranged to realize the translation and feeding of the C-shaped ring, and the second pressing mechanism is arranged to realize the continuous assembly of the C-shaped ring, so as to realize the axial locking of the rotating variable device in the rotor intermediate product.
